Scariest Game Ever

I don't find the Fallout games particulary scary, even though I am a Fallout freak. But sticking to the topic, other than Amnesia I forgot to write The Suffering, which I found pretty scary as a kid...and I still find it scary.

When I was a kid i played call of cthulhu and that got to me quite epic. and i been playing Dead space too and thats also pretty hectic too.
